What is UltraISO?

UltraISO is an application for Windows OS, produced by EZB Systems. The purpose of UltraISO is to create, modify, and convert an ISO image for optical disc authoring. Basically, the ISO image is a disk image for an optical disc.

In simple terms, UltraISO lets you open a disk image, which is a mere copy of the entire content of any storage device such as hard drive, CD/DVD, or USB.

Furthermore, Ultra ISO is a CD/DVD maker. That means, it can edit the CD/DVD, extract its data, and even make ISO files from it. Moreover, you can also create your own bootable device, maintaining the bootable information.

Is UltraISO Safe?

You must be wondering, is it safe to use UltraISO? So, the answer is yes. You don’t have to worry because UltraISO is pretty safe to download. It is entirely free of viruses, and it only serves to create virtual disk drives. Basically, UltraISO helps you to access the information present on disk images.

So, you won’t have to insert a disk once you have “mounted” the image file on the virtual drive. This phenomenon enables you to extract the data from disk images providing complete access to the information on CD, bypassing the need for the disk. Therefore, it’s safe.

However, there is a small issue of infringement. Since Ultra ISO allows you to open the disk image, it means you can even open the disk image that’s not yours. It may infringe the copyright of the actual owner of the media. Other than that, it is safe and legal.
